WebApr 8, 2010 · A Binary Search Tree has a very specific property: for any node X, X's key is larger than the key of any descendent of its left child, and smaller than the key of any descendant of its right child. A Binary Tree imposes no such restriction. A Binary Tree is simply a data structure with a 'key' element, and two children, say 'left' and 'right'. WebHowever, determining ancestor descendant relationship between any two nodes in a tree has not been addressed.
